TIFFANY STONE

SILVER RING

This is a natural untreated rough specimen of opal flourite from Utah Usa  .This material comes from a beryllium mine and it is becoming hard to mine in quantity.Tiffany Stone is composed of various minerals such as bertrandite , beryl, calcite, chalcedony, cobalt, dolomite, fluorite, manganese oxide, rhodonite, quartz, zinc and white opal potch. The purple color that characterizes Tiffany Stone was created by fluorine gases, while the striking black-colored veins were caused by manganese oxide; all of which were sealed within the sedimentary layers, becoming opalized over time. Tiffany Stone does not display any opalescence or colour play that is common in Australian opal.This material will fluoresce a bright green under short wave ultra violet light.It is best to use a mask when cutting this material.
